python - 显示不同时区的时间

Question

有没有一种优雅的方式来显示另一个时区的当前时间？

我想要一些具有以下一般精神的东西:

cur = <Get the current time, perhaps datetime.datetime.now()>
print("Local time   {}".format(cur))
print("Pacific time {}".format(<something like cur.tz('PST')>))
print("Israeli time {}".format(<something like cur.tz('IST')>))

Answer 1

更简单的方法:

from datetime import datetime
from pytz import timezone    

south_africa = timezone('Africa/Johannesburg')
sa_time = datetime.now(south_africa)
print sa_time.strftime('%Y-%m-%d_%H-%M-%S')
